Datasheet !!exclusive!! - Hw-133-v1.0

The HW-133-V1.0 is a compact, high-frequency DC-DC Step-Down (Buck) Converter module based on the MP1584EN control chip. It is widely used in hobbyist electronics, drone technology, and DIY projects where space is limited but power efficiency is critical.

  • SDA/SCL → 4.7 kΩ pull-ups to 3.3 V; series 33 Ω damping near module.

Compact Form Factor: Its tiny footprint (often 17x11mm depending on the specific V1.0 variant) makes it a "go-to" for hobbyists who find standard LM2596 boards too bulky. Hw-133-v1.0 Datasheet
